MACHINE FOR- COVERING WIRE.

SPECIFICATION forming part of Letters Patent No. 560,682, dated May 26, 1896.

Application filed July 11,

To cZZ whom it may concern:

Be it known that I, GEORGE L. BROWNELL,

. a citizen of the United States, residing at a larger scale.

Worcester, in the county of lVorcester and State of Massachusetts, have invented a new and useful Improvement in a Machine for Govering ire, of which the following is a specification, accompanied by drawings representing such portions of the machine as embody my invention, and in which Figure 1 represents a portion of the supporting-framework and so much of the mechanism as is concerned in winding a continuous strip of wire with the covering material and also the mechanism for drawing wire through the winding mechanism. Fig. 2 is a top view of one of the fliers. Fig. 3 is a side elevation of the same. Fig. i represents one of the tension-pins carried by the edge of the flier, the pin being shown in a raised position, in which it is disengaged from the flier. Fig. 5 is a top view of the compressor. Figs. 6 and 7 represent side and end views of the compressor. Fig. 8 is an elevation of the draft-wheel by which the wire is drawn through the fliers. Fig. 9 is a central sectional view on line 9 9, Fig. 1. Fig. 10is a similar sectional view of the draft-wheel on Fig. 11 is a side elevation of one of the fliers, showing the driving mechanism by which it is capable of being rotated in opposite directions. Fig. 12 is a detached view of cam K and hand-wheel P, showing the pivoted block and connecting-chain by which the rotation of the hand-wheel P is limited to one-half a revolution.

Similar letters refer to similar parts in the different figures.

My present invention relates to a machine for covering wire by winding it with a thread, cord, or similar material.

Referring to the drawings, A denotes a portion of the supporting-tramework. B B are revolving fliers carrying spools C O, holding the thread which is to be wound upon the wire. upon a reel D and conducted through the center of the fliers B B in the usual manner to winding mechanism, however, being of the The wire D to be covered is carried 1893. Serial No. 480,184. (N0 model.)

common form, is not shown in the accompany ing drawings. The fliers B B consist, in" the machine shown in the drawings, of two disks B and B attached to a central hollow spindle through which the strand of wire passes. Between the disks B and B is held the spool C, capable of turning within the flier and containing the winding material with which the wire is to be covered. The lower disk B is provided with a series of screw-threaded holes to receive the ends of tension-pins F, which are provided at their upper ends with enlarged sections or heads F, which fill circular notches F in the edge of the upper disk B the notches F being cut away, allowing the pin to be raised in the position shown in Fig. 4 and withdrawn from the disk B but when the tension-pins F are screwed into the disk B the head F will be brought into the circular portion of notch F filling the same and holding the upper end of the pin in position. Near the lower end of the pin is a milled flange F by which the pin is turned in order to unscrew it from the lower disk B.

The upper surface of the disk B is provided with an inclined wire F, Fig. 3, forming a rest over which the winding material passes from the tension-pins F to the wire. The disk B also carries two driving-screws F F, by which the compressor G is rotated.

The compressor Gis formed of two bars G and G held together by screws G and between the head of the screws and the bar G are placed springs G, which press the bars together. Between the bars G and G is an oblong opening G through which the wire passes, and the sides of the openings G are firmly clamped upon the strand of wire by means of the springs G. From the fliers B the strand of wire D is carried through dies H is the usual manner to the draft-wheel E, which is provided with a face I, over which the wire passes in contact with a shoulder I. The dies H are placed just above the compressors G and serve to prevent the compressors from being carried along by the moving wire and lifted out of the path of the drivingpins F F held in the fliers B. Arranged concentrically around the wheel E are a'series of eyebolts J, carrying adj Listing-nuts J, and to each of the eyebolts J is pivoted a radial lever J provided with a lip J 3 at right angles to the lever and projecting over the face I of the draft-wheel. At the hub of the draft-wheel is a concentric row of sliding pins K, which bear against the inner ends of the radial levers J 2 and which are carried by the rotation of the draft-wheel around in contact with the face of the cam K, by which the pins K are pushed against the levers during the upper third of their revolution, thereby rocking the levers J 2 and carrying the edges of the lips J 3 toward the shoulder I, securely clamping the strand of wire between. the shoulder I and the edges of the lips J and causing the strand of wire to be drawn forward by the rotation of the draft-wheel.

As the levers J which engage the strand of wire, move downward the pins K move off the cam-surface K, allowing the motion of the levers J 2 to be reversed by the action of the spiral springs held in the rim of the wheel E, thereby releasing the strand of wire.

- The fliers B are provided with pinions N, which are driven by gears N, having attached thereto a beveled pinion N which is engaged by the beveled pinions N and N upon the shafts N and N, which are driven through a belt connection in the usual manner.

The purpose of the two shafts N and N with their driving-pinions N and N is to provide means for rotating each of the fliers B in opposite directions, in one direction in order to wind the twine from the spool 0 upon the strand of wire and when the spool becomes empty to rotate the flier in the opposite direction in order to refill it. When the spool (J is to be refilled, the power is disconnected from the shaft N and applied to the shaft N, the screws F are removed from the annular flange a and inserted in the holes I) Z) in the disk B the screws passing through the upper disk against the head of the spool O, causing the spool to be rotated with the flier, the tension-pins F are then removed, a full spool c is placed upon a stud d, and the winding material unwound from the spool 0 onto the spool 0 without requiring the removal of the spool C from the flier.

During the operation of winding the strand of wire by the rotation of the fliers B the compressor is carried by the strand of wire itself and is driven by the contact of the driving screws F against the ends of the compressorbars, allowing the compressor Gr to assume a position relative to the flier as determined by the wire, so that the compressor will be rotated concentrically with the axis of the wire whether the wire be concentric with the flier or otherwise.

The draft-wheel E is driven by a pinion O on the shaft 0, rotated through a belt connection in the usual manner.

The cam K is held upon the shaft carrying the draft-wheel and has attached thereto a hand-wheel P, connected with a chain P and rod P with a pivoted block P held by the framework of the machine, the chain and rod holding the hand-wheel from rotating,

except through a half-revolution, as illustrated in Fig. 12, by which the cam K is turned, so as to release the wire at the top of the wheel E.

WVhat I claim as my invention, and desire to secure by Letters Patent, is

1. In a machine for covering wire, the combination with a revolving flier, having a hole concentric with its axis, through which the wire to be covered passes, said hole being larger than said wire, a pair of screws as F", projecting from said flier and a compressor having an opening G to inclose the wire, whereby said compressor-opening is held concentric with said wire, the ends of said compressor projecting into the paths of said screws, but being unattached thereto, wherebination with a flier provided with a concentric hole, through which the wire to be covered passes, screws, as F projecting from said flier, a compressor provided with an opening for the wire to be covered, the ends of said compressor extending into the paths of said screws F but unattached thereto, whereby said compressor is held with its opening concentric with the wire, and capable of a radial movement relative to said flier, and means by which said compressor is held from movement in the direction of the axis of the wire, substantially as described.

3. In a machine for covering wire, the compressor consisting of the bars G and G and having an opening G to receive the wire to be covered, screws G G each of said screws passing through one of the bars G, G and held in the opposite bar and spring G carried upon said screws, whereby said bars are pressed together and are capable of yielding to resistance brought against either of said bars, substantially as described.
